EBC GD Sport Front Rotors

2003–2004 Subaru Impreza 2.0 Turbo WRX STi

Part #: GD1056

Overview

The EBC GD Sport Front Rotors are a high-performance upgrade designed specifically for your Subaru Impreza WRX STi from 2003 to 2004. Crafted with precision and engineered for enthusiasts who demand both style and function, these rotors enhance your vehicle's braking capabilities while adding a sleek, aggressive look to your wheel setup. Whether you're daily driving, commuting, or engaging in spirited driving sessions, these rotors provide the cooling and durability needed to keep your brakes performing at their best.

Built with a focus on improved thermal management, the GD Sport rotors feature wide aperture slots that help dissipate heat more effectively during braking. This reduces the risk of brake fade, ensuring consistent stopping power even under demanding conditions. The dimple drilling pattern not only enhances heat dissipation but also helps prevent stress cracks, extending the lifespan of your rotors. Finished with a thermic black coating, these rotors resist corrosion and maintain their sleek appearance over time, making them an excellent choice for both performance and aesthetics.

Construction & Design

The EBC GD Sport rotors are meticulously engineered with a one-piece cast iron construction that ensures durability and consistent performance. The wide aperture slots are precisely machined to maximize airflow and heat dissipation, which is crucial during aggressive driving or frequent stop-and-go traffic. The dimple drilling pattern is strategically placed to prevent stress cracks, a common issue with high-performance rotors subjected to thermal cycling.

The thermic black coating not only provides a sleek aesthetic but also acts as a protective barrier against corrosion and rust, maintaining the rotors' appearance over time. The overall design emphasizes lightweight construction without sacrificing strength, helping to reduce unsprung mass and improve handling characteristics. These rotors are TIG-welded and finished to exact specifications, ensuring a perfect fit and reliable performance for your Subaru Impreza WRX STi.
